Entsha yoqobo ye-LM25118Q1MH/NOPB yeSekethe eDityanisiweyo ye-IC REG CTRLR BUCK 20TSSOP Ic Chip LM25118Q1MH/NOPB

1. I-synchronous bucking

Iingenelo.

Ukusebenza okuphezulu: ukuchasana kwangaphakathi kwetyhubhu ye-mos kuncinci kakhulu kwaye ukuhla kombane we-on-state kuncinci kakhulu kunokwehla kombane weCosmos we-Schottky diode.

Iingxaki.

Uzinzo olunganelanga: imfuno yokuyila isekethe yokuqhuba, kwaye ugweme ityhubhu ephezulu nasezantsi ngexesha elinye, isekethe inzima kakhulu, okukhokelela ekuzinzeni okunganeleyo.

2. impunzi engahambelaniyo

Iingenelo.

Ukusebenza okuphantsi: Ukuhla kombane we-Schottky diode kukhulu, xa kuthelekiswa nokusetyenziswa kwamandla okwenziwa ngumbhobho we-mos

Iingxaki.

Ukuzinza okuphezulu: akuyi kubakho ukuqhuba ngaxeshanye kwimibhobho ephezulu nangaphantsi.

1: PFM (indlela yokumodareyitha ipulse frequency)

Ukutshintsha ububanzi be-pulse ngokuqinisekileyo, ngokutshintsha ukuphindaphinda kwemveliso ye-pulse, i-voltage ephumayo izinzile.uhlobo lolawulo lunenzuzo yokusetyenziswa kwamandla aphantsi nangona isetyenziswe ixesha elide, ngakumbi kwimithwalo emincinci.

2: I-PWM (UkuModelwa kwePulse Width)

Uhlobo lolawulo lwe-PWM lusebenza kakuhle kwaye lunemveliso elungileyo ye-voltage ripple kunye nengxolo.

Ukushwankathela: Ngokubanzi, umahluko wokusebenza phakathi kwabaguquli beDC-DC abaneendlela ezimbini ezahlukeneyo zokumodareyitha, iPFM kunye nePWM, zezi zilandelayo.

PWM frequency, PFM duty duty cycle indlela yokukhetha.I-PWM/PFM yokuguqula uhlobo lolawulo lwe-PFM kwimithwalo emincinci kunye nokutshintshela ngokuzenzekelayo kulawulo lwe-PWM kwimithwalo enzima.

Nguwuphi umahluko phakathi kwe-ICs yokunyusa i-synchronous kunye ne-asynchronous boost ICs?

Umahluko ophambili phakathi kwe-ICs yokunyusa i-synchronous kunye nokunyuswa kwe-asynchronous ngumahluko kwiindlela zokulungisa.

I-synchronous boost IC circuit isebenzisa i-MOS kuba iityhubhu ze-MOS zinokuchasana okuphantsi kakhulu kwangaphakathi kwindawo evulekileyo kwaye ilahleko kwinkqubo yokulungiswa iphantsi kakhulu, ngoko ke ukusebenza kakuhle kwe-synchronous boost kuphezulu kwaye isizukulwana sobushushu siphantsi.Ingasetyenziselwa izicelo zokunyusa amandla aphezulu.

I-asynchronous boost IC circuits isebenzisa iidiode ukulungisa.Ii-Diode zine-voltage ye-junction yehla kwinkqubo yokulungiswa.Iphezulu yangoku kwinkqubo yokulungiswa, iphezulu ilahleko.Ngokuqhelekileyo, amandla akakwazi ukuba namandla aphezulu.
